Heritage Days 2025 at Rosny Rail (93), the Seine-Saint-Denis train museum

Are you a ferrovipathe, a train and railway enthusiast? If so, we've got the perfect museum for you! Head for Seine-Saint-Denis, and more specifically Rosny-sous-Bois, to discover the Rosny Rail museum on the occasion of Heritage Days 2025.

This little-known nugget is dedicated to the history of the railroads, from the late 19th century to the present day. The immersive museum features numerous installations, scale models, period objects, posters and signs, and even high-speed train components.

This museum is located under the Rosny-sous-Bois RER station, in formerly disused parts. Featuring dozens of antique exhibits, the museum's collection retraces the history of the railroads, and showcases model trains, reproductions of cockpits and country stations, and antiques.

  The ROSNY RAIL association was founded in 1997 by the SNCF (Direction Régionale de Paris-Est and Direction du Transilien ex Services Régionaux Voyageurs Île-de-France), the Musée Français du Chemin de Fer de Mulhouse (now the Cité du Train), the town of Rosny-sous-Bois and the Club Ferroviaire de Noisy-le-Sec. Its aim is to manage a museum designed to introduce the public (especially schoolchildren) to the history of the train, its past, its place in today's economy and its future prospects.

  Rosny Rail also aims to encourage Parisians to travel to Mulhouse to visit the Cité du Train, with which the association maintains close links, particularly in terms of museographic presentation.

  The association is responsible for the upkeep of the museum and its facilities, as well as for the acquisition, conservation and enhancement of the railway objects and equipment on display, both belonging to the museum and to third parties.

  Until the last few years, the ROSNY RAIL association has managed to carry out all these activities as best it could - with the dogged determination to keep a motorized draisine running on a track that is, alas, too short, as well as an engine powered solely by the arms of its visitors.
